Elites are already profiting from Trump’s victory. Are you?

About half of Americans own stocks, and they’ve already cashed in on Donald Trump’s surprise election in the 2016 presidential race. The Dow Jones Industrial Average has hit a new record high, with broader markets up a nifty 1.5% or so since Election Day. That translates into about $350 billion in new stock-market wealth.

A few sectors are doing much better. Bank stocks are up about 8% since Election Day, in the hope that Trump will follow through on his promise to loosen regulations on Wall Street firms like J.P. Morgan Chase (JPM), Citibank (C) and Bank of America (BAC). Until Nov. 9, investors expected the opposite, since Hillary Clinton, the now defeated favorite, had promised to tighten bank regulations, not loosen them. So banks are benefiting from an abrupt improvement in their earning prospects.

Other stock-market winners, so far: Pharmaceutical firms like Pfizer (PFE) and Merck (MRK), which may have a freer hand to hike drug prices under a Trump administration. Oil stocks such as Exxon Mobil (XOM) are up, since Trump has said he’ll kill many regulations that prevent drilling. And Caterpillar (CAT) shares have soared on the outlook for a big boost in spending on road and bridge projects.

Trump didn’t get elected to help the shareholder class, of course. But the nation’s haves are nonetheless first in line to benefit from many Trump policies intended to aid working- and middle-class families. Trump’s desire to help the nation’s “forgotten men and women,” as he calls them, may be genuine, but he will face the same problem as many before him: It’s devilishly hard to help those falling behind without first lining the pockets of the economy’s usual gatekeepers.

Boosting the fortunes of the shareholder class

Trump favors supply-side economic policies similar to those pursued by Ronald Reagan in the 1980s and George W. Bush in the early 2000s. In some ways he’d go even further, with substantial tax cuts for businesses and wealthy families. Small businesses and ordinary families would get tax cuts too, but lower taxes for those at the top will add substantially to the national debt and raise the government’s borrowing costs. That will become a drag on growth at some point.

Those tax cuts are supposed to free up more money for spending, and they will very likely boost growth for a while. But it’s a leap of faith to assume more spending will create a substantial number of new, good-paying jobs, especially with automation and software handling more and more work once done by humans. George W. Bush cut taxes in 2001 and 2003, but real GDP growth exceeded 4% only one year during Bush’s 8 years in office. Incomes stagnated under Bush, manufacturing employment declined every year and the 43rd president left office amid a daunting recession.
